DOI: 10.1002/mbo3.461
Abstract: Enterohemorrhagic Escherichia coli (EHEC) produces Shiga toxin 1 (Stx1) and Shiga toxin 2 (Stx2). Nitric oxide (NO), which acts as an antimicrobial defense molecule, was found to enhance the production of Stx1 and Stx2 in… read more here.

DOI: 10.1099/mgen.0.000879
Abstract: Dinoflagellates of the genus Alexandrium are responsible for harmful algal blooms and produce paralytic shellfish toxins (PSTs). Their very large and complex genomes make it challenging to identify the genes responsible for toxin synthesis. A… read more here.

DOI: 10.1128/msphere.00963-20
Abstract: Clostridioides difficile is the leading cause of antibiotic-associated diarrheal disease in the United States. During infection, C. difficile spores germinate, and the vegetative bacterial cells produce toxins that damage host tissue. In C. difficile, the… read more here.

Effects of stochasticity and division of labor in toxin production on two-strain bacterial competition in Escherichia coli
Sign Up to like & getrecommendations! Published in 2017 at "PLoS Biology"
DOI: 10.1371/journal.pbio.2001457
Abstract: In phenotypically heterogeneous microbial populations, the decision to adopt one or another phenotype is often stochastically regulated. However, how this stochasticity affects interactions between competing microbes in mixed communities is difficult to assess. One example… read more here.
